The non-limiting level of co2 is what I'm not sure about. What would be the effect of keeping co2 levels at 5 ppm if it was always replenished as fast as it was used?

ppm means parts per million, and is a way to express concentration. another way, more often used in chemistry is moles per liter, or molarity. a reactions speed depends in part, on its concentration. the higher the rate the faster the reaction occurs, photosynthesis included. so if you dont change the photoperiod, the higher the [CO2], the more photosynthesis occurs in a given day.

boraras are fun. youll like them.
the only thing i noticed is that even though they are properly sized for a nano, they seem much less comfortable than in a med sized tank. could be that they just dont like MY nano, however.

I have a treat for you guys today. To celebrate Week 4, I took some video from the phone for you to enjoy the layout a little more real than just photographic.

There's even a better step you can take to really enjoy the progress this tank has made along with me; if I could, I'd love to invite you into my home to enjoy it for yourself. Unless you're in the Houston area, the best I can do is share video and photographs with you.

What I'd like you to notice here is that there is no surface film since the last water change. This is a sign of the aquarium leveling out and progressing into balance.

You'll remember that the progress of this tank has had surface film form the very next day after water changes during this establishment period. To the point where a paper towel was deployed to remove the film!

Now a point has been reached where this film is not occuring, and is a sign that everything is going well - no decomposing, excellent oxygen / co2 exchange and healthy organisms.

Frank any reason why you chose the Maculates over the smaller and more red Brigittae? I'm just curious because I thought about going with the Brigettae but decided not to at the last minute. It's the smallest (I think) of the Rasbora and is so small that it looks great in a nano.

Great question!

The reason I went with Maculatus over Brigittae has nothing to do with the species (they're both great, I love the nano fish), but rather how they look.

The red's of the Brigittae was too dominate - I wanted more hues of red, and the coloration patterns of the Maculatus better aided in achieving what I was looking for: a fish that could contrast the bright greens while bringing out the accent colors of the tennellus.

Also, the Maculatus are here, so I'll be adding them to the tank tonight.

Since it will be the end of the day when they go to my aquarium, and since they have been in a box for a while I went ahead and put them in a bucket with a live plant.

Rather than acclimate them to a tank here, then re-acclimate them again with three different scenary changes in a day, I simply drip acclimated in some planted tank water from the 60-P at ADG, which is of similar quality to that of the water in my home.

They've been happily swimming about in circles and have colored up a bit.

They've eaten four times now ( small portions ) in 30 minutes with ADA AP-1 Gold and have regained their original color, especially the black spots. Once they fatten up a bit and develop their color will be amazing hues.

I can't describe the dynamism they add to the tank, anyone without fish in their setup is missing out! Adds a whole new zen flair!

Currently 2 bps on co2. Will be monitoring plants and animals for tr appropriate co2 balance.

ahhh I see...funny that's the same reason I wanted the Brigittae, just goes to show that everyone has a different view.

How many did you go with? I thought I could count close to 20 in one of your shots.
